Issue #12587 has been updated by Tomoyuki Chikanaga.


Hi, Antonio. Thank you for your comment.
The ruby tarball packages (including 2.3.x) don't require bootstrap ruby to build. (I've confirmed that it's correct to nobu).
I doubt that this issue is environment specific problem, especially related with Bash on Windows.

arton-san, please check your `make` recognize known_errors.inc correctly. I don't know how can I do it though...

----------------------------------------
Bug #12587: ruby released tarball require ruby
https://bugs.ruby-lang.org/issues/12587#change-59724

* Author: Akio Tajima
* Status: Open
* Priority: Normal
* Assignee: Nobuyoshi Nakada
* ruby -v: should be 2.3.1
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
I downloaded ruby-2.3.1.tar.bz2 into my brand new bash on windows.
I prepared gcc, autoconf etc but ruby itself because I know that ruby release tarball does not require ruby.
However, after hitting 'make', it stops while generating known_errors.inc because of 'executable host ruby is required. use --with-baseruby option.'.
